I have been talking to Jackkel Dragon and it seemed like this is not the first time the composer in the story did this.
I'm not a victim of some sorts but I have seen he did these kind of things before. Using music from TAM Music Factory, claimed as his own and selling them on Bandcamp.

Oh hey, just slipped in, can i have a request for any of these babies?
I really like your style hehe I hope we can do art trade once I improved more. (Oh hey, I realized you speak Vietnamese. Hello fellow Vietnamese-speaker <3)

Oh hey t0x3y from dA here. Never expected you to get out from dA and came to LSF. Love your works by the way. 1. Victor is a merma-man. Merman. I think so. Is he? I think John seems like the OTP? I don't really know. Every of your games have OTP. 2. More of your game is already enough for me. Totall...

I finished Penpal by Dathan Auerbach yesterday. I'm planning to pick up some horror titles to read in the next few days. I wonder if anyone have any recommendations for this? (Beside most classics titles and Stephen King, I have them on my list of books)

Oh hey, such a coincidence, I just saw your stunning works yesterday
Aha, I can't say much but I would choose VX because I'm using one right now
It looks very interesting so far x3 Good luck with your project <3

1) Would you want an option in the game to turn off any +18 nsfw content?
Yes, it would expand the audience 2) Don't have anything else, feel free to comment / critique
The art is very lovable so is the story, I'm looking forward for this

I have to agree with SundownKid about being a little pricey. Your anatomy seems to bit off for the price you have set in mind. The coloring, as said, need to work out more. But I think not everybody will have the same thought as I am. It might turn out well in fact :3
